Kari Lake has won the Republican primary for the Arizona Senate seat, defeating Pinal County Sheriff Mark Lamb by a significant margin. Lake, endorsed by former President Donald Trump, will face Democratic Rep. Ruben Gallego in the November general election. The race is pivotal for Senate control, with Democrats currently holding a narrow 51-49 majority. Gallego, who ran unopposed in his primary, has emphasized his commitment to abortion rights and other key issues. Lake's campaign, marked by substantial fundraising and controversial claims about past elections, faces challenges, including Gallego's financial advantage and broader voter skepticism. The outcome of this race will be closely watched as it could tilt the balance of power in the Senate.
